LA Fitness Cancellation for training West Covina, California

I signed up for an LA Fitness membership and started working out the next day. My first day in the gym a trainer had approached me and asked my friend and I if she could train us for the day. My friend and I agreed and figured its out first day in the gym and we are kind of lost anyways so why not. The trainer was amazing she had us doing all kinds of workouts and she was very knowledgeable. After the workout she starting talking to us and said she was new at the gym and trying to get clients. I used to do crossfit and was looking for something more hands on and different and figured a personal trainer would be beneficial. I thought about it the next couple days and was approached by one of the managers and was asked if i was interested in signing up for the training and to hurry because i wouldnt get the deal for being a new member.  I signed up that day and was really excited to start my training. I started my training with another trainer not the one i signed up with because she was still new. I didnt get my measurements until 2 months later and kept being swtiched from trainer to trainer. About 3 months into my training i got hurt at work and was advised by my doctor that i would not be able to do any training because it could affect my case. I am in the industry of workers comp and know the process and how everything works and decided i needed to cancel my training. I called member services and was advised to send in a letter or supporting documentation so it could be cancelled. My doctor wrote up a letter and i called member services back a couple weeks letter to confirm that if i do cancel that i can still use my accrued sessions at any time. The lady i spoke with said yes and to send in the letter. She asked if in the letter it states im 100% permanently disabled. I told her no because my case is fairly new and i havent been rated by my PTP or QME doctor. She explained to me the only way a membership could be cancelled for medical reasons is if the person is 100% permanently diasbled. I told her 100% disability is pretty much being handicapped. She said the sessions never expire so why cancel. I explained that being on disability doesnt pay a full salary and $170 for training is just not a necessity right now and i cant utilize any of my sessions for while. After arguing with this lady i told her i would put a stop payment on my card so i would no longer be charged since it is nearly impossible to cancel their training. She said she wouldnt recommend that because i would loose my 14 sessions that had accrued. I said WHAT?!?! your going to take away training sessions i already paid for and not reimburse me for them. She said thats how it works and if i do a stop payment i am still liable for the montly payment. I told her no i did not give my SSN therefore collections wouldnt do a whole lot. I can not believe that a company this large is screwing over their customers left and right by making it impossible to cancel training. She said it is California law that to cancel training you have to be 100% disabled. I highly doubt that is true and now have to go through the contract and see where it states all this giberish she was explaining. This needs to be brought to light that this is how LA Fitness works and all they want is your money and could care less about their customers.
